Catalogue Note

This spectacular gemstone was first sold at auction nearly nine years ago. It quickly soared to some six times its low estimate and was purchased by the celebrated jeweller Laurence Graff establishing a world record price at auction for a ruby of its size.

Mr Graff named the stone after the sale the ‘Graff Ruby’, and in a Bloomberg interview in February 2006 was quoted as saying ‘…the cut and spread of colour is the finest I have ever seen’.

Since then, the prices for truly exceptional Mogok rubies, arguably the rarest of all gemstones, have continued to soar on the very few occasions they have appeared on the market.
